An insulin pump is a device used for administering insulin in the treatment of diabetes .
The device consists principally of three parts :
- the pump itself including controls, processing module, and batteries
- delivery tube to carry the insulin
- needle inserted into the body
- a basal (small) dose that is delivered constantly
- a bolus dose that is delivered before meals or to correct high blood glucose levels
In all cases, delivery rates are determined by the user in consultation with his endocrinologist. Currently there is no means to automatically control the insulin delivery based on the blood glucose level of the user.
Use of insulin pumps is increasing as it provides an easier means to deliver multiple insulin injections for those using intensive insulinotherapy.
